Hold the extension brackets (ITEM 3) in place at the back of the rack, and then attach the brackets
to extension bracket mounts (ITEM 2) using Phillips head screws (ITEM 5), flat washers (ITEM 6), and
kep nuts (ITEM 7).
5.
Install screws (ITEM 8) through the extension brackets (ITEM 3) into the back of the rack rails. Secure
using #10 kep nuts (ITEM 7).
6.
Tighten all screws and nuts, securing the assembly.
7.
Insert the CMN-91 into either front opening of the DRC-2A. Slide the unit into the DRC-2A until it
seats fully against the back flanges of the DRC-2A, and the bezel of the CMN-91 is fully seated
around the front of the DRC-2A.
Because the CMN-91 is much shorter from front to back, it cannot seat against the back flanges of
the DRC-2A. Use the optional bracket kit to provide a back flange for the CMN-91.
8.
Secure the CMN-91 to the DRC-2A rack case using ½-in. Phillips head screws (ITEM 9) and tooth lock
washers (ITEM 10).
The installation is complete.
